Beschreibung

4-Amino-3-methylbenzenesulfonic acid is a sulfonation agent that is used to prepare sulfonic acids from amines. It is also used in the analysis of chlorinated aromatic compounds, such as 2-chloro-6-methylaniline, and can be used as an analytical reagent for determining functional groups. The reaction is carried out with hydrochloric acid and water vapor. 4-Amino-3-methylbenzenesulfonic acid can be prepared by diazotization of 2,4-dinitrochlorobenzene with sodium nitrite followed by hydrolysis with sodium hydroxide. 4-Amino-3-methylbenzenesulfonic acid reacts selectively with chloride ions and nitro compounds to form corresponding salts.
